Enable picture-in-picture mode in Android O

By default, picture-in-picture mode is disabled in the Android O developer preview, but it can easily be enabled in less than a minute.

Picture-in-picture (PiP) is a multitasking mode that was originally introduced last year for Android TV, but is now being brought to other devices with Android O. PiP mode allows users to watch a video in a floating window while doing other tasks in the background. Although the final release of Android O will include this mode, it has been disabled in the current early developer preview of the software. Within about a week of the preview's release, a method to enable PiP was discovered. If you're running the Android O developer preview on your Nexus or Pixel, here are the steps to enable PiP. Go to:

Settings
System
Systems UI Tuner
Navigation Bar
Enter 171 in the right or left keycode area

That's it; picture-in-picture mode should be enabled now. When in a supported app, press the right or left side of the navigation bar, depending on which side you entered 171 in. This will cause the supported app to transform into a small, draggable window. Since not many apps support PiP yet, expect at least a few bugs. But, by the time Android O is officially released, PiP should function as seamlessly as multi-window does.
